Yeah, I usually see it for seconds a year. If I saw it often enough to worry about theming it, I'd rather spend my time on fixing whatever caused me to have to see it so ofen.
So there is nothing to fix, the nice choice screen is a feature.
I say it is really nice not to have any problems with the boot process myself.
Ah I take it you don't have ADHD then? For me, it's not the 20 seconds - it's the fact that this time it might be the 2 minutes boot because it did an update in the background. So I'm happy to assume that any boot/reboot is 2 minutes long.
